ICE-CRUSHER.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed December 16, 1912. Serial No. 737,016.

To all whom t may concern Be it known that l, Joa-IN DEININGER, av

subject of the German Emperor, residing at UImpn-the-lanube, in Germany, have inventedcertain new and useful lmprovements in Ice-Crushers, of which the following is a specication.

This improvement. relates to ice Crushers as hand tools by means of which ice can be easily and quickly broken to small pieces, and which comprise a number of pointed pins secured to a plate and passing through a spring controlled plate which is adjust able in the direction of the pins, is guided by the same, and is pressed downward by springs. The said plate cooperates in crushing and prevents the series of pins from being choked, and the ice from splashing.

In the accompanying drawing in which the same reference letters indicate the same parts throughout, Figures l, 3 and 5 are vertical sections of such ice Crushers which differ from each other by the construction of the said spring plate. Figs. 2, 4L and 6 are bot-tom views of the ice Crushers in Figs. 1, 3 and 5, Fig. 7 is a cross-section on line A-B of Figs. 1, 3 and 5, Fig. 8 is a partial vertical section, showing another construction of means for limiting' the outward movement of the spring plate in Figs. 1 6, Fig. 9 is a cross-section on line C-D of Fig. 8, Fig. l0 is a partial vertical section of an ice Crusher shown in Figs. 1-6, showing another means for limiting the outward movement of the above spring plate.

According to Figs. 1-7, to the lower face of a plate b and at a right angle to the same, are secured the pins a: preferably made of steel and pointed at their free end, distributed as uniformly as possible. On the upper face of the plate Z) it is provided with a hub r in the center, and preferably with strengthening ribs s. In the hub r is secured at a right angle to the plate t, a tubular sleeve c. Into the lower open end of the said sleeve c projects loosely a head n mounted at the free end of a rod e which is secured at its other end to a spring plate. al (Figs. 1 and 2) or cl2 (Figs. 3 and 4) or Z3 (Figs. 5 and 6), of approximately the same size as the plate b and used for the above mentioned purpose. This spring plate is shown of diiferent construction in the figures, as will be hereinafter described.

lt is provided with holes /c through which the pins a pass loosely. Tt is guided, on the oneV hand, by means of the pins a, and on the other hand, by means of the above mentioned head a of the rod e in the sleeve c. ln the sleeve c is mounted a helical spring je pressing at the bottom against the head a, and at the top against a cotter pin /L connecting the free end of the sleeve to a handle g arranged concentrically with the same. The spring plate is therefore controlled by the action of the spring f which vhas the tendency to keep it in the end position shown in the drawing` and determined by the engagement of the heads p with the plate b. These heads 79 are mounted at the free end of bolts o secured to the upper face of the spring plate parallel to the pins a and passing through the plate b and used for further guidance of the spring plate. lf the spring plate is pressed toward the plate Z) to which it can be brought quite close, the former plate will be pushed back again into the end position illustrated, by the action of the spring f after the pressure ceases.

ln Figs. 8 and 9, the above mentioned bolts 0 are connected together, above the plate t, by a plate t which is provided in the center with a hole for the passage o-f the hub r. The bolts are in this case preferably in the planes of the ribs s which are then provided with bosses u for the passage of the bolts. The plate t vertically reciprocates with the spring plate, and by engagement with the ribs s limits the outward movement of the spring plate.

Another method of limiting this outward movement of the spring plate is shown in Fig. 10. The tubular sleeve c is reduced at the point o, and with the said reduced portion engages the above mentioned head a. ln that way, the plate b is not aected at all by the recoil of the spring plate. The ribs s are omitted, but of course may also be used.

The above mentioned. spring plate CZ is provided, according to Figs. 1 and 2, at the lower face with short pointed pins c' which participate in the crushing and render the ice smaller and finer.

Tn the construction shown in Figs. 3 and 4t, the spring blade Z2 is provided with a downward flange Z with sharp teeth m participating in the crushing of the ice.

In the construction shown in Figs. 5 and 6, the spring blade (Z3 is covered with short pointed pins and has moreover a downward flange Z with sharp teeth m.

The crushing of ice by means of the Crusher described, is eiected by seizing the handle g and making a ramming movement with the crusher against the pieces oic icey to be crushed; The pins a first split the pieces of ice, the spring plate CZ or cl2 or (Z3 being simultaneously raised. r0n the ice Crusher being raised for further blows, by which the split pieces of ice are reduced by the pins i and the pins z' or the teeth m, so that the action is a double one, the spring plate is projected each time by a spring f against the free ends of the pins a. In that way, it removes any bits of ice accumulating between the pins. The ice is very quickly and easily reduced to pulp as required ed pins on the lower surface of Vthezspring plate. 2. In an ice Crusher, comprising a main plate, a spring plate, pointed pins secured to the main plate and passing through holesA in the spring plate and guiding said spring plate, a spring adapted to separate the plates, means for counter-guiding the spring plate and means for limiting its outward movement, thecombination of a downwardly extending serrated flange upon the spring plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
